Micron Additives India Private Limited

Micron Additives India Private Limited is having the specific interest & experience in collecting, processing, classifying and marketing of Flyash as versatile additive for various applications including partial cement replacement.The details of various grades dealt by us are attached herewith for your information.Flyash is classified as a natural pozzolan and finds significant use as a cement additive. It has been found to increase the plasticity of the cement mixture while lowering the amount of mix water needed. In addition to improving levelling and finishing properties, flyash improves pumpability as well as decreases the heat of hydration of the concrete mix which is particularly important in massive concrete structures such as dams where the concrete needs to cool as quickly as possible.The Loss on Ignition (LOI) of flyash is an important quality when considering utilization. The LOI is primarily due to the presence of unburned carbon. The standard specifications for the use of flyash as a mineral admixture in Portland cement concrete are given in ASTM C618-89a. which sets an LOI limit of 6%; however, many states have set a more stringent limit of 3%. The primary reason for the lower LOI specification is that carbon adsorbs air, entraining agents which limit freeze-thaw resistance. This is particularly important in climates where multiple cycles of freezing and thawing are typical in winter.
